ABSTRACT:
The deposition of stickies on machinery used in the pulping and papermaking processes and in the final paper produced in the papermaking process using secondary or recycled paper is controlled by adding an amount of a water-soluble organotitnium(IV) compound to the aqueous system of a pulping and/or papermaking process, effective to reduce or remove the deposition of the stickies on the machinery and the resulting paper.
